' HENRY SCHNACKENBERG, OF CRESCO, PENNSYLVANIA DRINKING CUP.

Application med September 10, 1921. Serial mi, 499,619.

To all'whom itm'ay concern: Be it known that I, HENRY SGHNAOKEN- BERG, acitizen of the United States, and a residentof Cresco, in the county ofMonroe and State of Pennsylvania, have invented a new and ImprovedDrinking Cup, of which the following is a description.

My invention relates to paper drinking cups and more particularly to adrinking cup in which the bottom isformedby overlapped. tongues integralwith'the cup and bent into position to form a closure of the cup at thebottom.

The general object offmy invention is to provide a cup of the indicatedcharacter improved in various particulars to the end that the cup willbe reinforced atthe bottom, the cup being further characterizedby anovel arrangement of thetongues constitutingthe bottom.

Reference is to be had to the accompany-- ing drawing: forming a part ofthis specification, it ings are merel illustrative of practical examplesof the invention.

Figure 1 is a vertical section of a drinking cup formed in accordancewith my invention, as indicated-by the line 1--1, Figure 2; r v

Figure 2 is a horizontaljsection on the line 22, Figure 1;

Figure 3 is a planview of the blank that may be utilized for forming thecup and in which the slits dividing thetongues are 7 body so that thereinforce flares upwardly carried through the reinforcing zone;

Figure 4 is a vertical section of the lower portion of the cup, the cuphaving the bot-- tom slightly modified as referred'to hereinafter;

Figure 5 is a fragmentary view showing a portion of. the blank andmodified so that tice of-wax paper as is usual in the trade andin'practice the blank, as shown in Figures 3 and 4, from which the cupbody is formed is made with a flange 11 at one side terminating short ofthe bottom of the blank and adapted to overlap the opposite ed e whenthe blank is bent to form a round b y. The bottom designatedgenerally-by the numeral 12 is elevated above the lower edge of the bodyso thatlthe latter has an' ing understoodthat the draw-v annularsustaining bottom edge 13 below the bottom.

The bottom 12 is formed of tongues 14 I 'to a point 15, said point beingformed at the juncture of two adjacent tongues and pronounccdly nearerto one side edge of the blank than to the other; The edge formed jointlyby the tongue ends presenting a long curve 16 and a short curve 16*. Thepurpose of the described arrangement of the tongues isto produce anapproximate uniformity throughout the bottom.12 and prevent ac-'cumulated material at the center by reason of too great a pluralityofoverlapping tongue parts.

In association with the bottom as described, I form the blank 10 with areinforcing zone 17 scored on two lines 18, 18 The slits 19separating'the tongues may extend through the reinforcing zone 17 as inFigure 3 or as shown in Figure 5 the slits 19) may terminate at thereinforcing zone 17*) making said zone unslitted. In forming the cupfrom the blank the latter is in correspondence with the body. In Figure4 I have shown the modified arrangement in which the upturned zone 17 isturned up in cylindrical form so as to be spaced from the flaring body10 of the cup therebyleaving an annular channel between the reinforcingzone and the body into which the wax may run in the coating of a thecup.

In practice the tongues 14 are caused to adhere to' each other by theapplication thereto of a suitable adhesive materiafwhich reduces thetongues to a limp condition whereupon b the pressure of a mandrel, thetongues are attened out into a single plane to form in effect aomogeneous bottom.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the exact details herein an annular channeltherebetween for receiving Wax.

2. A drinking cup formed of a blank and having the bottom formed of aplurality of tongues integral with the body and overlapping to form a.closure of the cup, said tongues bein of increasing length from the sideedges ot the cup to a point nearer one side edge than the other.

3. A drinking cup formed of a blank and having the bottom formed of aplurality of tongues integral with the body and overlapping to form aclosure of the cup. said tongues being of increasing length from theside edges of the cup to a point nearer one side edge than' the other,the ends of the said tongues increasing slightl from a side edge of thebody oithe-cup toward the opposite edge, the increase in tongues jointlypresenting curves terminating at said point.

4:. A drinking cup having the bottom formed with a plurality of tonguesoverlapping and forming a closure of the cup, in length length beingmore abrupt toward a point short of the opposite side edge.

5. A drinking cup having the bottom formed with a plurality of tonguesoverlapping and forming a closure of the cup, said tongues increasingslightly in length from i a- 'side edge ofthe' body of the cup'towardthe opposite edge, the increase in length being more abrupt toward apoint short of the opposite side edge, and those tongues between thesaid point and the opposite side edge decreasing in length toward saidopposite edge.

(5. A drinking qup having a bottom formed with a plurality of tonguesoverlapping and forming a closure of the cup, said tongues increasing inlength from a side edge of the bodyot' the cup to a point short of theopposite edge, the end edges of the tongue bein on a curved line.
